To all whofm it may concern.

, Be it known that I, .1 OHN FOSTER STEPHEN- SON, a subject of the Queenof Great Britain, anda resident of Cranmore street, Glenferrie, in theColony of Victoria, have invented certain new and useful Improvements inor Connected with the Supporting-Frames of Bedstea'cls, of which thefollowing is a specificatiOfi:

I provide what I have herein termed a socket-piece namely, a metal bosshaving a cavity to be fitted upon a bedstead-post and a shoe or boxformed in it to receive the wooden rail of a spring-mattress and withnovel means of securing the rail in place. In some cases the post has acone formation to receive the socket-piece and means of locking same inposition. By the use of my invention the ordinary metal dovetailed railsare dispensed With and a cheaper and better construction is provided.

In order to make myinvention clear, I shall now refer to theaccompanying sheet of drawings, in which- I Figure 1 shows a plan of apost provided with socket-piece; Fig. 2, a vertical section of same;Fig. 3, an elevation of asocket-piece detached from the standard; Fig.4, an elevation of portion of the post, showing the cone for thesocket-piece. Fig. 5 shows the end frame of a bedstead to which myinvention is applied, one of the socket-pieces being shown in positionfor packing and one in position to receive the rail of aspring-mattress. Fig. 6 shows a form of connection of a socket-piece anda bed post in which the cone formation isdispensed with and showing alsomeans for holding the rail in the shoe. Fig. 7shows plan of the shoeportion of the socket-piece with the means for holding the rail in theshoe.

in which a conical cavity or socket b is formed. Two or more keyways areformed in this cavity, preferably one at the forward portion 0 and oneat each side d e. The socket-piece is formed with the box or shoe f toreceive the rail of a springmattress, said socket-piece having a closedbottom and sides and an open top. A lateral holding-tooth g is providedon the bottom of the socket to form a hold upon the rail, and the saidbottom has a hole Z to receive the bolt, which secures the rail in position. I v

it represents a post or standard of a bed; stead andwhich has securedupon it or made intimate'iwith it a metal cone t, which is arranged tofit into the cavity of the socket piece aforesaid. This cone has a keyIt upon it, which corresponds with the keyways c d c and is adapted toenter either of said keyways.

In securing together a bedstead provided with the improvements the postit is passed through the conical cavity 1) of the'socketpiece untilstopped by the cone t' upon said post, the socket-piece being thussupported. The key being brought into position in the keyway c (if sodesired) will lock the joint, with the shoe in position to receive theframe of the mattress or a rail of the bed.

When bedstead-frames provided with my improvements are to be packed, thesocketpieces may be raised off their cones and turned around intotheposition shown at the left in Fig. 5, the key 70 in this case restingin the keyway c. I may'employ two keyways onlynamely, one at the frontand one at one side of the socket.

I- prefer the means illustrated on Figs. 6 and 7 for holding the railsof a spring-mattress in their respective shoes. Z represents thebolt-hole before referred to, through which passes a bolt which ispassed through the rail, such bolt being secured by a nut beneath theshoe. m represents a stud, which is set upon the shoe in front of andsubstantiallyin line with the bolt-hole Z. This stud may have aslightly-conical taper. The stud enters a corresponding recess formed onthe under side of the rail, so that the bolt and stud will together forma secure hold upon the rail to prevent any movement thereof Within theIn the drawings, or represents a socket-piece.

shoe.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. The combination with a standard having a cone formedthereon and provided with a key, of a socket-piece having a conicalcavity arranged to fit over said cone, and provided with a plurality ofkeyways arranged to receive said key, and means carried by saidsoeket-piece for engaging a rail, substantially as set forth.

2. The combination with a standard having a cone formed thereon andprovided with a key, of a socket-piece having a conical cavity arrangedto fit over said cone, and provided with a plurality of keyways arrangedto receive said key, a shoe formed with said socketpiece and having aclosed bottom and sides and an open top, and a stud projecting from [6the bottom of said shoe, substantially as set forth.
